Field Detail

digester

protected Digester digester

The Digester with which this Rule is associated.

namespaceURI

protected String namespaceURI

The namespace URI for which this Rule is relevant, if any.

Constructor Detail

Rule

public Rule(Digester digester)

Deprecated. The digester instance is now set in the Digester.addRule(java.lang.String, org.apache.tomcat.util.digester.Rule) method. Use Rule() instead.

Constructor sets the associated Digester.

Parameters:

digester - The digester with which this rule is associated

Rule

public Rule()

Base constructor. Now the digester will be set when the rule is added.

Method Detail

getDigester

public Digester getDigester()

Return the Digester with which this Rule is associated.

setDigester

public void setDigester(Digester digester)

Set the Digester with which this Rule is associated.

getNamespaceURI

public String getNamespaceURI()

Return the namespace URI for which this Rule is relevant, if any.

setNamespaceURI

public void setNamespaceURI(String namespaceURI)

Set the namespace URI for which this Rule is relevant, if any.

Parameters:

namespaceURI - Namespace URI for which this Rule is relevant, or null to match independent of namespace.

begin

public void begin(Attributes attributes)
           throws Exception

Deprecated. Use the begin method with namespace and name parameters instead.

This method is called when the beginning of a matching XML element is encountered.

Parameters:

attributes - The attribute list of this element

Throws:

Exception

begin

public void begin(String namespace,
                  String name,
                  Attributes attributes)
           throws Exception

This method is called when the beginning of a matching XML element is encountered. The default implementation delegates to the deprecated method begin without the namespace and name parameters, to retain backwards compatibility.

Parameters:

namespace - the namespace URI of the matching element, or an empty string if the parser is not namespace aware or the element has no namespace

name - the local name if the parser is namespace aware, or just the element name otherwise

attributes - The attribute list of this element

Throws:

Exception

Since:

Digester 1.4

body

public void body(String text)
          throws Exception

Deprecated. Use the body method with namespace and name parameters instead.

This method is called when the body of a matching XML element is encountered. If the element has no body, this method is not called at all.

Parameters:

text - The text of the body of this element

Throws:

Exception

body

public void body(String namespace,
                 String name,
                 String text)
          throws Exception

This method is called when the body of a matching XML element is encountered. If the element has no body, this method is not called at all. The default implementation delegates to the deprecated method body without the namespace and name parameters, to retain backwards compatibility.

Parameters:

namespace - the namespace URI of the matching element, or an empty string if the parser is not namespace aware or the element has no namespace

name - the local name if the parser is namespace aware, or just the element name otherwise

text - The text of the body of this element

         throws Exception

This method is called when the end of a matching XML element is encountered. The default implementation delegates to the deprecated method end without the namespace and name parameters, to retain backwards compatibility.

Parameters:

namespace - the namespace URI of the matching element, or an empty string if the parser is not namespace aware or the element has no namespace

name - the local name if the parser is namespace aware, or just the element name otherwise

Throws:

Exception
